        <h1>Scroller example <span>Server-side processing (5,000,000 rows)</span></h1>

        <div class="info">
            <p>DataTables' server-side processing mode is a feature that naturally fits in with Scroller perfectly.
                Server-side processing can be used to show large data sets, with the server being used to do the data
                processing, and Scroller optimising the display of the data in a scrolling viewport.</p>

            <p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling
                to finish before requesting more data from the server (200mS by default). This prevents you from DoSing
                your own server!</p>

            <p>This example shows Scroller using server-side processing mode and 5 million rows.
                <strong>Important</strong> This particular example uses <a href=
                                                                                   "//datatables.net/reference/option/ajax"><code
                        class="option" title=
                        "DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the
                data to
                show Scroller's ability to show large data sets. It does not have a real database behind it! You would
                normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title=
                        "DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate
                data, but
                rather as a url for where to fetch the real data!</p>

            <p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end
                user what is happening when they scroll passed the currently loaded data.</p>
